Harassment covers a wide range of behaviors of offensive nature. It is commonly understood as behavior that demeans, humiliates, and intimidates a person. The continuity or repetitiveness and the aspect of distressing, alarming or threatening may distinguish it from insult. When these behaviors become repetitive, it is defined as bullying.
Bullying is the use of force, threat, or coercion to abuse, intimidate, or aggressively dominate others. It is often repeated and habitual. One essential prerequisite is the perception, by the bully or by others, of an imbalance of social or physical power. Behaviors used to assert such domination can include verbal harassment or threat, physical assault or coercion, and such acts may be directed repeatedly towards particular targets.
